Market Leading Triple Glazed Windows

Aluminium clad timber windows combine the practicality of aluminium on the outside with the classic appeal of wood on the inside – a high end item that is stylish, long lasting, and energy efficient.

Our triple glazed, timber aluminium clad windows have a modern appearance and are suitable for all types of Northampton homes. They offer energy efficiency along with durability, performance, and style.  As with all of our products, these flush casement windows are of the highest calibre. They are triple glazed, so you won’t need to turn up the heat in the winter to keep your Northampton house warm.

Low Maintenance

These windows are triple glazed as standard in a 48mm sealed unit, which makes them incredibly energy efficient and adds comfort to your home. 

Depending on your needs, our flush casement windows can be top-hung or side-hung and open outward.  Fixtures can be made up to 3 metres high if you need big glass panes to maximise solar gain.  We can create single opening windows up to 1.5m x 1.5m and also provide an inward opening tilt and turn system.

Customise Your Windows

The interior wood of the windows adds warmth to any house and can be painted or lacquered in a variety of colours to match a desired colour scheme or a specific design theme of your Northampton property. The triple glazed windows come in a variety of wood species, including Pine, Spruce, engineered Redwood, Accoya, and European Oak, in addition to a wide range of colours.

The exterior aluminium gives off a contemporary vibe and requires almost no maintenance, so your windows will continue to look fantastic for many years. We provide an extensive selection of RAL powder coated colours in a variety of finishes, giving you limitless triple glazing options.

Thermal Efficiency

Depending on the glazing specification, aluminium clad timber windows have excellent thermal performance, achieving u values as low as 0.79 (W/m2K).  A timber window with an aluminium clad that has received Passivhaus certification can achieve an U-value of up to 0.66 (W/m2K). We are proud to offer double and triple glazing options to all our customers.

Our aluminium clad timber windows not only offer good thermal performance, but they also give you peace of mind because they have been tested to PAS 24:2016, which means they are also extremely secure and have been Secured By Design certified.

Our amazing showroom in Bradwell Abbey, Milton Keynes, is filled with a variety of intriguing products. Please contact us to make a triple glazing appointment to visit our showroom, which is only open by appointment.

What Do Our Customers Say?

Excellent and prompt service from Infinite Windows & Doors when we opted to use them to provide our bifold doors. The builder who is building our extension failed to sort them through his “usual” window company so we cast out on our own and found Infinite. I’m very glad we did. The doors arrived earlier than expected, and were fitted in the course of an afternoon. They look fabulous and will look even better when the rest of the extension build is completed!

S. Thomas

Amazing knowledge from the salesperson, great clarity of documentation, customer service, installation and quality of products. Highly recommend. So refreshing to deal with a professional, approachable Company who practice integrity.

W. Rust

From start to finish we have been impressed by the professionalism and enthusiasm of the team at Infinite Windows & Doors Ltd. Their price was competitive. They worked quickly, neatly and efficiently and the standard of finish was excellent. Everyone was polite and friendly and we can highly recommend them.

E. Chua

Colin, Jamie and Jackie are a great team and a joy to work with. I introduce all my clients to them, knowing they will receive one to one attention throughout the whole process. They know their products inside out from pricing, technically to fitting on site. They work with the Architect throughout the process, providing CAD details. They work to ensure that the process is as simple and efficient as possible.

We can thoroughly recommend them.
